Dismissed notifications can be activated + * by clicking on their anchorElement. + * eventCallback: + * Callback to be invoked when the notification changes + * state. The callback's first argument is a string + * identifying the state change: + * "dismissed": notification has been dismissed by the + * user (e.g. by clicking away or switching + * tabs) + * "removed": notification has been removed (due to + * location change or user action) + * "showing": notification is about to be shown + * (this can be fired multiple times as + * notifications are dismissed and re-shown) + * If the callback returns true, the notification + * will be dismissed. + * "shown": notification has been shown (this can be fired + * multiple times as notifications are dismissed + * and re-shown) + * "swapping": the docshell of the browser that created + * the notification is about to be swapped to + * another browser. A second parameter contains + * the browser that is receiving the docshell, + * so that the event callback can transfer stuff + * specific to this notification. + * If the callback returns true, the notification + * will be moved to the new browser. + * If the callback isn't implemented, returns false, + * or doesn't return any value, the notification + * will be removed. + * neverShow: Indicate that no popup should be shown for this + * notification. Useful for just showing the anchor icon. + * removeOnDismissal: + * Notifications with this parameter set to true will be + * removed when they would have otherwise been dismissed + * (i.e. any time the popup is closed due to user + * interaction). + * checkbox: An object that allows you to add a checkbox and + * control its behavior with these fields: + * label: + * (required) Label to be shown next to the checkbox. + * checked: + * (optional) Whether the checkbox should be checked + * by default. Defaults to false. + * checkedState: + * (optional) An object that allows you to customize + * the notification state when the checkbox is checked. + * disableMainAction: + * (optional) Whether the mainAction is disabled. + * Defaults to false. + * warningLabel: + * (optional) A (warning) text that is shown below the + * checkbox. Pass null to hide. + * uncheckedState: + * (optional) An object that allows you to customize + * the notification state when the checkbox is not checked. + * Has the same attributes as checkedState. + * hideNotNow: If true, indicates that the 'Not Now' menuitem should + * not be shown. If 'Not Now' is hidden, it needs to be + * replaced by another 'do nothing' item, so providing at + * least one secondary action is required; and one of the + * actions needs to have the 'dismiss' property set to true. + * popupIconClass: + * A string. A class (or space separated list of classes) + * that will be applied to the icon in the popup so that + * several notifications using the same panel can use + * different icons. + * popupIconURL: + * A string. URL of the image to be displayed in the popup. + * Normally specified in CSS using list-style-image and the + * .popup-notification-icon[popupid=...] selector. + * learnMoreURL: + * A string URL. Setting this property will make the + * prompt display a "Learn More" link that, when clicked, + * opens the URL in a new tab. + * displayURI: + * The nsIURI of the page the notification came + * from.
